Murry Bergtraum, the national powerhouse and 12-time city champion, fell twice to out-of-state teams at coach Ed Grezinsky’s holiday event. Saying two home losses in two days is a rarity for Bergtraum would be an understatement.

Lincoln pulled a couple of upsets at the Baseline Holiday Madness Tournament, defeating Truman and Medgar Evers en route to the title – and now a No. 8 ranking. The Railsplitters can do more damage Friday against Francis Lewis, No. 1 Bergtraum meets No. 6 Manhattan Center on Wednesday and No. 7 Banneker hosts No. 10 Medgar Evers on Monday. Should be another big week.

Here’s how the rankings look:

1. Murry Bergtraum (8-2) (Last week: 1)

It was one of the roughest weeks for Bergtraum in a long, long time. The Lady Blazers, ranked No. 8 in the country by USA Today, had fourth-quarter leads on both No. 23 St. John’s College and Connecticut powerhouse Hillhouse at the Bergtraum Holiday Classic and ended up losing both games. While two home defeats in two days for coach Ed Grezinsky’s team is about as rare as Haley’s Comet, Bergtraum is going to be extremely battle-tested come February and March.

Next: @ No. 6 Manhattan Center (Jan. 5, 5 p.m.)

2. South Shore (6-3) (2)

While most of the city’s teams braved the inclement weather early last week, South Shore coach Anwar Gladden was sipping hot cocoa and reading NYPost.com – literally. The Vikings will be back in action for the first time since a tough loss to Teaneck two weeks ago on Wednesday against Gladden’s alma mater, Midwood.

Next: Midwood (Jan. 5, 5 p.m.)

3. John F. Kennedy (8-6) (3)

The season’s sequence has gone like this for Kennedy: Big game, let down, big game, let down. The Knights fought hard with Bergtraum for four quarters before two lethargic non-league games against Paterson (N.J.) John F. Kennedy and St. Anthony’s (L.I.) before Christmas. The same thing happened last week. Coach O’Neil Glenn’s team beat Corcoran, the team it lost to by 30 last year, at the Amsterdam Upstate vs. Downstate Holiday Classic only to lay an egg the next day against Shaker.

Next: Truman (Jan. 5, 5 p.m.)

4. Francis Lewis (6-4) (4)

The Patriots were never able to make it up to the Amsterdam Upstate vs. Downstate Holiday Classic last week due to the snow. They did make it to the Bergtraum Holiday Classic, though, where they fought hard Wednesday against nationally ranked St. John’s College (D.C.) without star junior guard Jasmine Davis, who could be a big absentee Friday in a game against surging Lincoln.

Next: Beach Channel (Jan. 5, 5 p.m.)

5. McKee/S.I. Tech (10-3) (5)

The snow ruined star junior Kaitlyn Astel’s chance of getting her 1,000th career point at home when MSIT’s game last Tuesday against Baruch College Campus was canceled. She got it the next day in a loss to Sachem East at the Bergtraum Holiday Classic. The Seagulls rebounded on Thursday with a blowout of Truman back in Lower Manhattan.

Next: @ Petrides (Jan. 6, 4:30 p.m.)

6. Manhattan Center (5-7) (6)

After a series of heartbreaks, Manhattan Center finally got a solid win Thursday when it beat Midwood. Better yet, senior forward Brea Castro Gambrell is starting to come on. She had 23 points and 10 rebounds against the Hornets and is primed for a big second half of the season. The Lady Rams get another shot at archrival Bergtraum on Wednesday.

Next: No. 1 Murry Bergtraum (Jan. 5, 5 p.m.)

7. Banneker (7-5) (7)

The Warriors continue to be one of the best stories of the season. They didn’t fare well in a loss to tough Holy Trinity (L.I.) on Thursday, but a day earlier they beat solid New Mission (Mass.), a team that beat Grand Street on Thursday. Super sophomore Africa Williams is still scoring at a prodigious pace.

Next: No. 10 Medgar Evers (Jan. 3, 5 p.m.)

8. Lincoln (5-3) (NR)

The holiday break was very good to Lincoln – and we’re not talking about the gifts Santa brought. The Railsplitters put it all together last week, beating School of the Future, then-ranked Truman and No. 10 Medgar Evers to win the Baseline Holiday Madness Tournament. Defensive dynamo Erica Juarbe won the MVP award and sophomore point guard Simone Roberts has been a revelation. First-year coaches Titi Hodges and Ciara Shields can raise their team’s stock even more Friday with a win over Francis Lewis.

Next: Madison (Jan. 5, 5 p.m.)

9. Grand Street Campus (7-5) (8)

The Wolves hobbled into the holidays and didn’t recover there either. Last week, Grand Street got routed by Holy Trinity (L.I.) and New Mission (Mass.) at the Big Apple Christmas Classic at Nazareth. It looks like coach Corey McFarlane never did get that point guard for Christmas. He and assistant Dinero Young have to go back to the drawing board to see what’s going wrong.

Next: @ Boys & Girls (Jan. 5, 5 p.m.)

10. Medgar Evers (7-3) (9)

Senior guard Ashley Castle has been the best player on the court for many of the Cougars’ games this season, but even she couldn’t lead them over balanced Lincoln in the Baseline Holiday Madness Tournament final last Thursday. Castle scored all of her team’s 13 second-half points. Coach Barney Davis’ squad will be looking to rebound Monday against Banneker.
